Companies that make textiles, apparel, and furniture would benefit the most from solar energy, according to new research.

U.S. manufacturing takes up a lot of energy, but there’s untapped potential in solar power for that sector, new research finds. A study looked at how installing solar panels throughout manufacturing sites could meet a third of that sector’s power needs.

Researchers used a survey from the Department of Energy and compared states to understand where rooftop solar could best supply electricity needs for manufacturing. They found that companies that focus on textiles, apparel, and furniture would benefit the most from transitioning to solar energy. Their work is published in the journal Environmental Research: Sustainability and Infrastructure.

The researchers used a statistical model to discover the suite of technologies that would minimize land impacts.

Imagine that all 462 billion watts of electricity consumed in the United States last year were supplied by a single source of power, rather than a mixture of different technologies. This is how much land each power source would require.

If nuclear power plants generated all U.S. electricity, that would occupy 469 square miles of land, including the land for mining uranium, storing spent fuel and connecting to the electricity grid.

That’s about the size of Madison County, Idaho, population 53,000.

Environmental groups argue that the CPUC acted illegally when it slashed compensation payments for power generated by solar panels.

The fate of California’s wildly successful rooftop solar incentives will be decided in court.

In a lawsuit filed Wednesday — and shared exclusively with The Times — three environmental groups argue that the California Public Utilities Commission acted illegally when it slashed compensation payments for power generated by solar panels. Gov. Gavin Newsom’s appointees failed to consider all the benefits of rooftop solar, and also ignored instructions from the state Legislature to ensure that solar adoption “continues to grow sustainably,” the environmental groups say in their lawsuit.

They’ve asked the California Court of Appeals to throw out the Public Utilities Commission’s December decision and order the agency to go back to the drawing board.

The flat, open, sunny roofs of medium and large warehouses and distribution centers are perfect locations for solar panels.

Solar power is getting cheaper and more efficient all the time, and America should take advantage of untapped solar energy opportunities, including the billions of square feet of warehouse rooftops across the country.

Solar power is the fastest growing form of energy in the United States, thanks in large part to its low and rapidly dropping price and to supportive public policies in some parts of the country. But the United States has the technical potential to produce 78 times as much electricity as it used in 2020 just with solar photovoltaic (PV) energy. To quickly and sustainably achieve a future of 100% renewable energy, America must take advantage of untapped solar energy opportunities.

Former Gov. Arnold Schwarzenegger and a crowd of more than 100 people celebrated a completed solar rooftop project at AltaSea.

The flood of sunshine in San Pedro on Friday morning, April 21, was apt, as as former Gov. Arnold Schwarzenegger and a crowd of more than 100 people celebrated a completed solar rooftop project at AltaSea, the marine science lab at the Port of Los Angeles.

The 180,000-foot panels cover four acres of rooftop on the old port warehouses that now are now home to the ambitious, 35-acre research hub, the largest such center in the nation dedicated to creating and powering ocean-based jobs in the emerging blue economy.

Schwarzenegger, who climbed the scaffolding steps and did the honors to turn on the rooftop solar project that will power the AltaSea campus and 700 local homes, marveled at the campus’s progress.

Residential rooftop solar supplied a record 14% of Australia’s electricity this summer – contributing more than brown coal and more than large-scale wind farms and solar projects.

The total output of rooftop solar in Australia over the summer was 8,046 GWh, up 19.5% on the preceding year, according to the Clean Energy Council.

The Clean Energy Council says that an increase of 15% to 20% in Australian electricity bills in 2022 underpinned strong demand for rooftop solar. Rising power prices also made rooftop solar’s payback times even more attractive.

“We’re seeing a fundamental shift; consumers are becoming energy generators,” said Clean Energy Council Chief Executive Kane Thornton, noting that these figures only measure what enters the grid.

A solar panel the size of 18 football pitches is currently being built in the Falken tyre manufacturing facility in Thailand.

Falken is building the world’s most extensive solar panel installation on a single facility, covering an area of 100,000 square metres, which is equivalent to over 18 football pitches. This installation is being constructed at the Sumitomo Rubber Industries (SRI) factory in Thailand, where Falken is a subsidiary.

The installation is composed of 40,000 solar panels with a combined output of 22MW and is set to be completed by January 2025. By then, the facility will be able to use 100% renewable energy, thanks to the investment in the new solar panel installation, as well as the adoption of a gas co-generation system and biomass electric power system initiatives at the Rayong Province facility. The gas co-generation system, which comprises two 6.6MW boilers powered by renewable energy sources, will replace energy supplied by local utility companies. Additionally, biomass obtained from the surplus branches and trunks after rubber trees are harvested, as part of SRI’s Sustainable Natural Rubber⁴ programme, will provide additional electrical power.

Dozens of groups will tell the CPUP to revise the new rooftop solar plan to make solar more affordable for low-income communities.

California regulators should revise a new rooftop solar plan to make solar more affordable for low-income communities, dozens of groups will tell the California Public Utilities Commission at its meeting Thursday. The commission’s plan drastically slashes the credit new solar users would get for sharing their extra solar energy with the grid.

More than 100 groups are urging the commission to delay implementation of the plan until it can resolve issues raised in an administrative appeal for rehearing filed in January by the Center for Biological Diversity, Protect Our Communities Foundation and the Environmental Working Group.

Rooftop solar advocates opposed to the CPUC's recent decision are petitioning for a chance to be heard again.

Rooftop solar advocates opposed to the California Public Utilities Commission’s (CPUC) recent decision to cut the amount new solar users will be compensated for supplying power to the grid are petitioning for a chance to be reheard.

Following months of hearings in 2022 that included hours of public comment mostly against the CPUC’s decision, attorneys for two groups filed requests with the CPUC for a chance to argue again. Tri-Valley advocates of rooftop solar agreed that the CPUC should revisit its decision.

In a 25-page application for rehearing filed Jan. 17, Michael Boyd, president of Californians for Renewable Energy (CARE), accuses California Gov. Gavin Newsom of conspiring with CPUC board members to violate state and federal antitrust measures that benefit the state’s three largest public utilities, including Pacific Gas & Electric, which serves Northern California.

Almost one-third of homes have panels in Australia, the highest in the world, says SunWiz, and will soon outpace capacity from coal.

Australia’s rooftops now boast 20 gigawatts of solar panels and will soon have the capacity to produce more electricity than the country’s entire coal industry, according to the industry consultancy SunWiz.

Almost one in three Australian households have solar photovoltaics – or solar panels – the highest penetration in the world. Queensland had the highest share of solar panels installed on dwellings deemed suitable for the technology with an 82% penetration, ahead of South Australia’s 78%, New South Wales’ 51% and Victoria’s 43%.

The take-up of solar PV has quickened. It took about 11 years for Australia to reach its first 10GW of capacity, while the second 10GW took just four years, according to SunWiz.
